was wondering about adcom due to their lower cost,are they inferior or a better deal.i liked the hca1000a ,just didnt need it anymore,,i saw an gfa545 for alot less and thought would make a good xmas gift if it is a good buy

I would choose neither. I would look for an Odyssey Audio or Muse 100 or maybe Bryston and get a smoother, cleaner, and tighter bass response with less etching or hardness on the top end than either the Adcom or Parasound. If you have a friend that has any of their products check them out. I'm sure you will like them.

I had a pair of Magnepan 3.3Rs.I tried them with (2) Adcom 555IIs,and (2) Parasound HCA1200As.The Parasounds were a newer design, and sounded less forward than the Adcoms.This was confirmed when I tried the same amps on my Counterpoint Clearfield Monitors. This speaker had the same aluninum Vifa tweeter as the early 3 series Thiels,(before they went to the propietary concentric tweeter/midrange).The Adcoms were just plain unpleasant on the Vifa tweeter.

The HCA-1500a is a nice amp for the money. It's significantly better than the HCA-1201 and the Adcoms you mention. To my ears, in my system, it compared favorably with a McCormack DNA-1. It has great control over the bass and isn't as harsh on the top end as some SS amps I've heard. However, there are smoother SS amps I would consider first like Odyssey Stratos or Belles 150A
